Claims (2)

248 296 OF THE INVENTION A method for producing foundry cheese cores by thickening a sintering mass by pressing, characterized in that the molding material is thickened by molding, forming half cores while forming a temporary compressed portion and excess volume deposited between the molded portion and the cores of the cores and small compared to with the volume of the core to attain the strength of the future core, and then the compressed portion separates and the surface of the excess volume, contributing the core halves to the core, is roughened and then the cores corresponding to the cores are joined to the core by molding excess volume. 2. Method according to claim 1, characterized in that the excess volume is increased, depending on the volume of the core halves, a few mm above the separating plane and a small thickness on the contour plate is formed by pressing the molding material overlaying the excess volume template. the molding tool, followed by separating the temporarily compressed portion in the lower portion of the counter plate on the template side of the excess volume and removing the excess volume template.
